Question

1. Employers often use standardized measures to gauge how likely it is that a new employee with little to no experience will succeed in their company. One such factor is intelligence, measured using the Intelligence Quotient (IQ). To show that this factor is related to job success, an organizational psychologist measures the IQ score and job performance (in units sold per day) in a sample of 10 new employees.

IQ	Job Performance
100	20
115	35
108	22
98	15
120	42
147	54
132	45
85	60
105	28
110	38

(a) Convert the following data to ranks and then compute a Spearman correlation coefficient. (Round your answer to three decimal places.)


(b) Using a two-tailed test at a 0.05 level of significance, state the decision to retain or reject the null hypothesis.

2. A therapist specializing in family counseling measures the relationship between partners and marital satisfaction. Husbands and wives rated how satisfied they were in their marriage using a 7-point rating scale ranging from 1 (not satisfied at all) to 7 (very satisfied). Using the hypothetical data given in the following table, compute the Pearson correlation coefficient. (Round your answer to three decimal places.)

Husband	Wife
X	Y
1	6
2	6
3	6
4	6
5	6
6	6
